Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

PNEC (freshwater sediment):

K(susp-water) = 0.905 m³/m³

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_freshwater sediment = (Ksusp-water) / RHOsusp) * PNEC (freshwater) * 1000

= (0.905/1150) * 0.1 * 1000

= 0.0787 mg/kg wwt

= 0.362 mg/kg dwt

The PNEC (freshwater sediment) of dry weight (dw) is 0.362 mg/kg corresponding to the wet weight (ww) value of 0.0787 mg/kg (conversion factor: 4.6).

PNEC (marine sediment):

K(susp-water) = 0.905 m³/m³

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_freshwater sediment = (Ksusp-water) / RHOsusp) * PNEC (marine water) * 1000

= (0.905/1150) * 0.01 * 1000

= 0.0079 mg/kg wwt

= 0.0362 mg/kg dwt

The PNEC (marine water - sediment) of dry weight (dw) is 0.0362 mg/kg corresponding to the wet weight (ww) value of 0.0079 mg/kg (conversion factor: 4.6).

PNEC soil:

K(soil-water) = 0.206 m³/m³

RHO(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

PNEC_soil

= (K(soil-water) / RHOsoil) * PNEC (freshwater) * 1000

= (0.206/1700) * 0.1 * 1000

= 0.0121 mg/kg wwt

= 0.0137 mg/kg dwt

The PNEC (soil) of dry weight (dw) is 0.0137 mg/kg corresponding to the wet weight (ww) value of 0.0121 mg/kg (conversion factor: 1.13).

Conclusion on classification

Aquatic acute toxicity


48 h, EC50 (Daphnia magna): >100 mg/L (nominal)


72 h, ErC50 (Raphidocelis subcapitata) >100 mg/L (nominal)


96 h, LC50 (Danio rerio): >100.0 mg/L (nominal)


 


Aquatic chronic toxicity


72 h, ErC10 (Raphidocelis subcapitata): >100 mg/L (nominal)


 


Biodegradation: Inherently biodegradable: 48.6 % after 28 days (OECD 301D)


 


Classification according to CLP


Based on the data above, the substance has not to be classified for short-term (acute) or long-term (chronic) toxicity according to the seventeenth ATP (Regulation (EU) 2021/849) of the Regulation (EC) No 1272/2008 (CLP).
